Example for SF_MutingPar_2Sensor with two reflecting light barriers
1
If reflection light barriers are used as muting sensors, they are generally arranged diagonally. In general, this
arrangement of reflection light barriers as muting sensors requires only two light barriers, and only
S_MutingSwitch11 (MS_11) and S_MutingSwitch12 (MS_12) are allocated.
Muting conditions
Muting condition 1 (to 8011) (MS_11 is the first entry switch actuated). Start timer DiscTimeEntry and Max-
MutingTime:
MutingEnable AND R_TRIG at MS_11 AND NOT MS_12
Muting condition 2 (to 8311) (MS_12 is the first entry switch actuated). Start timer DiscTimeEntry and Max-
MutingTime:
MutingEnable AND NOT MS_11 AND R_TRIG at MS_12
Muting condition 3 (from 8011 to 8012) (MS_12 is the second entry switch actuated):
Stop timer DiscTimeEntry:
MutingEnable AND MS_11 AND R_TRIG at MS_12
